What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting This study
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.

Summary

This study looks at whether starting trans-anal irrigation (a procedure that uses warm water to help empty the bowel) within three months of stoma closure reduces daily bowel movements more than starting later. The trial involves 250 adults who have had rectal cancer surgery and now suffer from low anterior resection syndrome (LARS), which causes frequent, urgent, or uncontrolled bowel movements. Participants are trained to use a device at home and are followed for nine months to track symptoms, quality of life, and satisfaction.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Water-based transanal irrigation system (Peristeen® Plus device)
What this could lead to
If early irrigation works better, it could establish a new standard timing for managing bowel symptoms after rectal cancer surgery, improving daily comfort and quality of life.
What could go wrong
This is a mid-sized trial comparing two timing strategies, not a new treatment. The benefit may be modest, and individual results vary. The procedure requires daily commitment and may cause discomfort.
